Mozilla releases latest Firefox browser

Mozilla on Wednesday released an update to resolve six vulnerabilities, two rated as critical, in its Firefox web browser.

Version 2.0.0.13 staves off the possibility of spoofing, cross-site scripting and malicious code installation that could result from exploitation.

The most serious flaw appears to involve a JavaScript privilege escalation problem, according to the SANS Internet Storm Center. This could force the browser to run malicious scripts that could lead to cross-site scripting or arbitrary code execution.

Storm Center handler Raul Siles wrote on the group’s blog that users should consider running the open-source NoScript extension, offered by InformAction, to protect against attacks.

The other critical bug that was patched relates to a memory corruption error.

Mozilla also released version 1.1.9 of internet suite SeaMonkey and version 2.0.0.13 of email client Thunderbird.
